142 LOWER OOLITIC BOOKS OF ENGLAND: 
In reference to the strata on Ebrington Hill, Prof. Judd re- 
marks that the beds of the Inferior Oolite, which constitute an 
outlying mass, consist mainly of yellow and brown, somewhat 
siliceous and coarsely oolitic limestone-rock, and exhibit in places 
ferruginous banding like that of the Northampton Sand. Some 
of the beds are composed of a ferruginous shelly rock, in places 
almost wholly made up of plates of Pentacrinus, with abundant 
specimens of Pecten personatus, Trigonia stgnata, Terebratula 
perovalis, &c. In one of the pits he noticed a very instructive 
section. At its southern end are yellow and ferruginous sands, 
a little to the northward irregular hard beds occur in these sands, 
and slill farther north the whole passes into a calciferous sand- 
stone rock with ironstone-banding ; in fact there is presented, in 
one section, " examples of the different aspects which the North- 
ampton Sand assumes at various points. Still further north, 
however, the rock becomes more and mora oolitic in structure, 
and thus passes into the ordinary oolitic limestone which caps the 
hill. All these changes take place within a distance of about 40 
yards. Everywhere on this outlier of Ebrington Hill, the lime- 
stones of the Lower Freestones may be seen to assume arenaceous 
characters, thus graduating in places into calcareous sand-rock, cr 
or into sandy calcareous stone with some imperfect cellular iron- 
stone." Prof. Judd adds, that above Ilmington Downs, on the 
north side of the Hill, we find the ordinary yellow freestones 
passing down into beds of sand, sometimes containing " pot-lids," 
and graduating into a mass of fissile calcareo-siliceous rock with 
ferruginous banding Beds similar to these are found above 
Stoke Wood. In the extensive pits above Little Hilcote, courses 
of the fine oolitic rock with ferruginous banding, occur, sometimes 
interstratified with beds of sand. At the rabbit-warren above 
Great Hilcote, though no good faces of rock are exposed, the 
strata, which constitute the lower part of the Inferior Oolite, are 
seen to consist of yellowish-red, calcareo-ferruginous sand, with 
layers of fissile, iron-banded, calcareo-siliceous stone. These beds, 
he says, are undistinguishable in character from many portions of 
the Northampton Sand, as seen in Oxfordshire and Northampton- 
shire.* 
Although the sands and soft sandstones of the Midford Beds 
have been traced along the northern borders of the Cotteswold 
Hills, no traces of the Cephalopoda Bed have been observed. 
The junction with the Upper Lias clay was exposed on Cadley 
Hill, above Batsford, as follows :

Further south near Seizincote, the sands and calcareous saua 
stones were observed by Prof. Hull.f (See p. 12.)
